Forces

Force is a

• Push or pull

• Mass and weight

• Only a strong push

• Only a strong pull

The two components of force are

• Push and pull

• Direction and volume

• Speed and direction

• Direction and magnitude

Weight is

• How much matter something has

• A measurement of gravitational force

• How heavy something is

• Anything that has volume

A balanced force has

• The most strength

• The least strength

• A net force of 0

• A net force of greater than 0

Force applied to objects that are not touching

• Non-touching force

• Contact force

• Anti-force

• Non-contact force

Two people push a piano with forces of 130 N to the right and 150 N to the left. What are the strength and direction of the net force on the piano?

• 280 N left

• 20 N left

• 280 N right

• 20 N right

The amount of matter in an object

• Volume

• Weight

• Mass

• Density

If an astronaut moved away from Earth in the direction of the Moon, how would the gravitational force between the Moon and the astronaut change?

• It would stay the same

• It would decrease

• It would increase

• It would double

Kilograms is the SI unit for measuring

• Weight

• Volume

• Acceleration

• Mass

The sum of all the forces on an object is

• Weight

• Mass

• Net force

• Unbalanced force
